Friend of mine has a set installed on his 6.2L GMC Sierra. He added magnaflow mufflers. Sounds outstanding. Quality is unmatched. Only thing is it throws a code about once a week. According to the diablo programmer its related to the cats. Is there a remedy? Should I consider shortys? Would like go with ARH and factory muffler.

after a long tube install on a computer controlled vehicle you need to have it properly tuned not only to take care of any codes but to get the most performance out of the system as well. The truck will run fine without the tune but a tune will help imensely
